What Is The Difference Between The Inner And Outer Core Of The Earth??
The inner core and the outer core are made up of similar stuff chemically (both are made mostly of iron with a little nickel and some other chemical elements)–the difference between them is that the outer core is liquid and the inner core is solid.Nov 11 2014
What is the major difference between the inner and outer core How was it determined?
Main Difference: The main difference between the inner core and outer core of the earth is that inner core of the earth is the innermost layer of our planet whereas outer core is the layer that surrounds the inner core.
What is the difference in the physical form of the inner and outer core?
The inner core is solid the outer core is liquid and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core silicate crust and mantle) and the increase in temperature and pressure as depth increases.
What is the difference between the inner and outer mantle?
What is outer and inner core?
What is meant by inner core?
(planetology) The solid material found in the centre of some planets at extremely high temperature and pressure distinct from the liquid outer core. (geology) The innermost part of the Earth believed to be made of a nickel-iron alloy.
What is the outer core do?
What is hotter inner core or outer core?
The inner core is indeed hotter than the outer core. However the PRESSURE on the inner core is greater than the pressure on the outer core and the melting point of iron the main constituent of the core INCREASES as the pressure goes up.
How is the outer core of Earth different from the inner core quizlet?
What is the principal difference between the inner core and outer core? The inner core is liquid while the outer core is solid.
What is difference between crust and core?
The crust is the outermost layer of the earth. The core is the innermost layer of the earth. Crust is about 60 km thick below high mountains and just 5-10 km below the oceans. … Core has very high temperature ranging from 4400°C to about 6000°C.
What is the difference between crust mantle and core?
Earth’s Layers (The internal structure of the Earth)
The crust is a silicate solid the mantle is a viscous molten rock the outer core is a viscous liquid and the inner core is a dense solid.
Which earth layer is located between the outer core and the crust?
What is in the inner core of Earth?
At the center of the Earth is the core which has two parts. The solid inner core of iron has a radius of about 760 miles (about 1 220 km) according to NASA. It is surrounded by a liquid outer core composed of a nickel-iron alloy. … The inner core spins at a different speed than the rest of the planet.
Where is the outer core of Earth?
What is inside the Earth?
The Earth’s interior is composed of four layers three solid and one liquid—not magma but molten metal nearly as hot as the surface of the sun. The deepest layer is a solid iron ball about 1 500 miles (2 400 kilometers) in diameter. Although this inner core is white hot the pressure is so high the iron cannot melt.
What is the outermost layer of the Earth?
the crust
The outermost layer called the crust is solid too. Together these solid parts are called the lithosphere. Earth’s crust is made up of hard rocks. It is the only part of the Earth that humans see.May 20 2015

Is Earth’s inner core solid?
What is a fact about the inner core?
What are 5 facts about the inner core?
- It’s Almost The Size of the Moon. The Earth’s inner core is surprisingly large measuring 2 440 km (1 516 miles) across. …
- It’s Hot…Really Hot. …
- It’s Mostly Made of Iron. …
- It Spins Faster Than the Surface of the Earth. …
- It Creates a Magnetic Field.
Which layer is solid and hotter Earth’s inner core or outer core?
The inner core is actually solid despite it’s hotter than the sun’s surface thanks to the atomic diffusion of iron at high pressure. Meanwhile the outer core is liquid made of molten iron in constant churning movement driven by convection as the outer core loses heat to the static mantle.
Why is the inner core solid and outer liquid?
Earth´s inner core and outer core are both made of an iron-nickel alloy. … As you go deeper in the Earth both temperature and pressure increases. Although the inner core is very hot it is solid because it is experiencing very high pressure. The pressure in the outer core is not high enough to make it solid.
Is the Earth’s core solid or liquid?
The core of the Earth is made up mainly of iron in an outer liquid layer and an inner solid layer. The outer core is where the circulating conducting liquid generates the geodynamo responsible for our magnetic field.
What is the inner core quizlet?
Inner core. Is in the centre and is the hottest part of the. Earth. It is solid and made up of iron and nickel.
What is the inner core of the Earth quizlet?
Earth’s inner core is composed mostly of solid copper. At about 5 000 degrees celsius the inner core is the hottest part of the Earth. Earths’s outer core is composed mostly of molten mercury.
Why is Earth’s outer core hotter than Earth’s oceanic crust?
Earth’s oceanic crust is denser than Earth’s outer core is. Earth’s oceanic crust has lava flowing from the mantle. Earth’s outer core has a composition of solid iron and nickel.
What are two differences between the crust and the inner core?
In geology a crust is the outermost shell of a rocky planet like Earth (as opposed to a gaseous planet like Jupiter). … The inner core was discovered in 1936 by Danish seismologist Inge Lehmann and is believed to be made up of about 80% iron (by comparison only about 4% of the Earth’s crust is made up of iron).
What are the differences between biosphere and hydrosphere?
The biosphere is the part of the earth and its atmosphere capable of supporting life while hydrosphere is all the waters of the earth as distinguished from the land and the gases of the atmosphere.
What is CL and Seema?
Sial is composed of silicon and aluminium.It is upper layer which forms a discontinuous cover over the Earth’s crust and is entirely absent the ocean floor. Sima is composed of silicon and magnesium. This is the second layer below sial which forms the ocean base. It is also called oceanic crust.
What is interior layer of the earth?
What layer of the Earth has an inner and outer portion?
The core is the centre of the earth and is made up of two parts: the liquid outer core and solid inner core. The outer core is made of nickel iron and molten rock.
What are 3 differences between continental crust and oceanic crust?
Continental crust is low in density whereas oceanic crust has a higher density. Continental crust is thicker on the contrary the oceanic crust is thinner. Continental crust floats on magma freely but oceanic crust floats on magma scarcely. Continental crust cannot recycle whereas oceanic crust can recycle it.
How does the inner structure of the earth affect its surface?
Each layer has a unique chemical composition physical state and can impact life on Earth’s surface. Movement in the mantle caused by variations in heat from the core cause the plates to shift which can cause earthquakes and volcanic eruptions.
How does the inner core affect all of the Earth’s other layers?
Lasting Effects: With the heavy inner core the earth’s orbit and rotation will remain stable over the long term giving us day and night and summer and winter. … These swirling convection currents result in the earth’s magnetic field which keeps us properly oriented for travel and shields earth from deadly cosmic rays.
